CUT-OUT FOR VEHICLE-MOTORS.

the motors of motor-driven vehicles, such as automobiles and motor-cycles; and has for its object the production. of a device of this character which will be of durable and economical construction, one which may be readily and easily installed, one which may be easily operated, and one which will be highly efficient in use.

Other objects will appear hereinafter. 'With these objects in view, the invention consists in the combinations and arrangeforming a part ments of parts hereinafter described and claimed.

" The invention will be best understood by reference to the accompanying drawings of this specification, and in which, 5

The form of the construction, illustrated in the drawings, is shown applied to a conventional motor-cycle having cylinders 10 and exhaust pipes 11 leading therefrom to a muffler 1 Interposed in each of the exhaust pipes 11 is a cut-out mechanism or valve embodyingthe invention in question, the cut-out devices interposed in said pipes 11 being similar. Each comprises a substantially rectangular body or housing 12 formed at its Specification of Letters Patent.

opposite ends with openings and flanges 13 surrounding said openings for the reception of the ends of the exhaustpipes between which the device is inserted. Set screws 14 are provided for securely fastening the member 12 to said ends of the exhaust pipe.

Arranged in the housing 12 is a blade or flap valve 15 of a width such that said blade snugly fits between the sidesof said housing, as clearly shown in Figs. 5 and 7. The lower end of said blade is mounted upon a shaft 16 which is rotatably mounted in housing 12, said blade being securely locked thereto by means of a set screw 17. The arrangement is such that said blade, when in vertical position, or that shown in full lines in Fig. 4, is adapted to tightly close a laterally facing opening 18 which is formed in the front side of housing 12; and, when said blade is rocked inwardly to its inner terminal of movement, as seen in dotted lines in Fig. 4, the opening 18 will be uncovered, the exhaust passage through the housing traversed, and said blade, assuming an inclined position, will be adapted to deflect any gases passing through the exhaust pipe outwardly through the opening 18, thus serving to cut-out the muffler of the vehicle. j

The blade 15' is normally held in vertical position, or in a position in which the passage through the housing 12 is uninterrupted, by means of a helical torsional. spring 19. Provided upon one of the exteriorly projecting ends of the shaft 16 of each of the blades 15, is a rocker arm 20, the arms 20 of the two cut-out devices, being operatively connected by a conne-ting rod 21 and cooperating connecting forks 22, as seen in the several views. With this arrangement, the blades or valves 15 of the two devices will operate in unison, both opening and closing simultaneously.

Connected with one of the arms 20 is a chain 23 which is connected, at its lower end, with a laterally projecting arm 24 carried at the outer end of a pedal 25 whi h is hingedly conne"ted at 26 with a leaf or base member 27 rigidly secured to the upper side of the running-board 28 of the motor-cycle, adjacent the front end thereof. The arrangement is such, as will be seen, that rocking of the blades or valve members 15 to operative or cut-out position, may be effected by simply depressing the pedal 25, such depression being readily effected through engagement therewith of thefoot of the operator.

For the purpose of locking the blades or valve members in operative or cut-out position, a keeper 29 is provided which is pivotally mounted at upon the running '1 board 28, adjacent the pedal 25. The for- Ward end of keeper-.29 is adapted to rest loosely upon the upper side of arm 24. Upon depression, however, of the forward end of said keeper, a shoulder 31, provided at the under side thereof, Will engage with the rearward edge of the arni'24, shown in dotted lines in Fig. 2, and thus said keeper Will serve to lock the 'arm 24; in depressed position and. hence the blade or valve members 15 in cut-out position. I

With a construction, as set forth, used in connection with a vehicle motor, choking of the motor may be overcome by simply momentarily cutting out the niutller so as to permit of uninterrupted exhaust of the discharging gases from the motor. Also, the opening of'the cut-outwill increase the sound incident to explosions in the niotoi'cylii'iders,

said increase in sound being adapted to serve as'an alarin'signal, thus avoiding the necessity of horns or otheradditional devices for :th s purpose. The provision of means for locking the cut-out device's in operative position is of special advantage in connection with racers here, asis known, mufl'lers are not'e np'loyc'd, applicant "s construction makingit possible'to employ a motor-cycle for racing purposes without-the necessity of detaching the inuil'leig or cutting off the ex 1mm.

pipes as necessary at the present time; n p

In order to permit of theuse otan extension pipe to carry'the exhaust gases discharging through the openings 18, back to the rear of the motor-cycle or vehicle, each of the housings 12 is formed, at its rearward side, with lugs 32, as seen in Figs. 4:, 5 and 7.

'While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not Wish to be limitedto the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.

Having described my invention What I claim as new and desire to secure by Letters Patent is:

The combination with a motor driven \'e hicle having an exhaust pipe leading from the vehicle motor, of a normally closed cut out valve interposed in said pipe; means for operating said cut out valve comprising a rockingly mounted foot pedal adapted,- when rockingly depressed, to move said valve to open position; a rockingly mounted keeper arranged adjacent to and at one side of said pedal, the, axis of said keeper being spaced above the aXis of said pedal; a laterally pr, jecting arm on said pedal extending under said keeper and a shoulder on said keeper adapted, upon depression of said pedal, to engage with said arm to lock said pedal in this position, substantially as described.

ln testimony whereof I have signed my name to this specification inthc presence of two subscribing Witnesses. BYRON Gr. STICKNE i Witnesses:
